Explanation

HTTP 1.1 allows the use of multiple virtual servers, all using different DNS names resolved by the same IP address. The WWW service supports a concept called virtual server. A virtual server can be used to host multiple domain names on the same physical Web server. Using virtual servers, multiple FTP sites and Web sites can be hosted on a single computer. It means that there is no need to allocate different computers and software packages for each site. Answer: D is incorrect. VPN stands for virtual private network. It allows users to use the Internet as a secure pipeline to their corporate local area networks (LANs). Remote users can dial-in to any local Internet Service Provider (ISP) and initiate a VPN session to connect to their corporate LAN over the Internet. Companies using VPNs significantly reduce long-distance dial-up charges. VPNs also provide remote employees with an inexpensive way of remaining connected to their company's LAN for extended periods. Answer: B is incorrect. Java is an object oriented programming language developed by Sun Microsystems. It allows the creation of platform independent executables. Java source code files are compiled into a format known as bytecode (files with .class extension). Java supports programming for the Internet in the form of Java applets. Java applets can be executed on a computer having a Java interpreter and a run-time environment known as Java Virtual Machine (JVM). Java Virtual Machines (JVMs) are available for most operating systems, including UNIX, Macintosh OS, and Windows. Answer: C is incorrect. HTML stands for Hypertext Markup Language. It is a set of markup symbols or codes used to create Web pages and define formatting specifications. The markup tells the Web browser how to display the content of the Web page.
